Hello I am Referbing a 87 mustang and just started today. I would like to know a round about cost to have a body shop put in new floor boards and if a body shop would tackle that project. I really only need the passenger side done and not the whole side but just the front. and also what is the best way to take care of a rusted out spot on the rear passenger side fender right at the bottom. and the molding Kinda in the middle of the body is popping out a bit how would you go about fixing that. any help is great
